For my Ph.D. thesis I'm looking at royal inscriptions from Mesopotamia (ancient Iraq), and part of what I'm trying to do is analyze their spatial distribution - i.e. how many were found at which archaeological site. I'd like to create a map to illustrate this, with a visual indication of the quantity of objects found, e.g.: Kish - 20 objects Ur - 100 objects Uruk - 2 objects etc etc.
I have an excel spreadsheet with the site names, their lat/lon, and the quantity of objects found there.
Can someone point me in the right direction for how to change this data into a visual representation?
